I need/would like to take an existing .jpg and convert it to a favicon.ico. I've tried this all afternoon, with no success whatsoever.

The last two (2) things I tried were a Firefox add-on, image2icon and a Web site, http://www.generatefavicon.com/, both to no return. I've tried every Website/service I could find for this conversion. I have Axialis' Icon Workshop. All of these things purport to perform the conversion I desire. They don't - or, at least, they haven't.

So, anyone with a pregnant idea? One that might give birth to a working product?

No, I cannot create the damned thing myself ... when it comes to visual design, anyone else with just one (1) eye is likely to outperform me. I stink at endeavors artistic.
